My proposal would be to add a new # directive that would be used the file to be included. I imagine this being used mostly for all of the various function libraries out there that are typically included. My suggestion would be to use something like
#namespace <namespace>. When that file is included, all of its variables/functions/classes would be found under that single namespace. I suppose an alternative would be to simply wrap all of the variables/functions/classes into a class and use them all as static definitions.
Maybe its not a good idea. Just thought it might help with the issue of global namespace pollution... and with people prefixing their functions with weird things like initials and etc.
